Bolivia’s government says it considers Yanky Ostreicher a fugitive after unknown groups helped him flee across the border into Peru, the AP reports.

Justice Minister Cecilia Allyon said in a press conference today that she doesn’t know whether the U.S. government played a role in Ostreicher’s escape. She said Bolivia is alerting Interpol. Allyon said Ostreicher entered Peru illegally and then boarded a U.S.-bound plane on Monday, according to the AP.
